Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If two-dimensional codes are transmitted and stored in graphic forms, then information can be visually presented, but communication resources are occupied more, communication time is longer, and communication cost is higher
Solution Approach 1:
The patent changes the fundamental parameter of code representation from graphical pixels to text characters. By encoding two-dimensional code data as text strings rather than image files, the communication format is transformed to reduce resource consumption while maintaining information integrity and visual presentation capability through screen display.
2Loss of information
If two-dimensional codes are transmitted and stored in graphic forms, then information can be visually presented, but communication cost is higher
Solution Approach 1:
The patent transforms the communication parameter from image file transmission to text message transmission. This parameter change reduces communication cost because text messages consume less network bandwidth and transmission energy compared to graphical images, while still achieving effective information delivery through character-based display.
3Reliability
If two-dimensional code images are stored in mobile terminal memory, then codes can be stored for later use, but memory capacity is relatively large
Solution Approach 1:
The patent changes the storage parameter from binary image data to text character data. Text-based storage requires significantly less memory capacity than graphical image storage while maintaining the same reliability for code retrieval and usage. The information density per byte is improved by representing visual patterns as compact character sequences.
4Reliability
If two-dimensional code images are stored in mobile terminal memory, then codes can be stored for later use, but it is difficult for customers to quickly and accurately find out needed codes
Solution Approach 1:
The patent transforms the retrieval parameter from image recognition to text searching. Text-based code representation enables customers to quickly find needed codes through character-based search and identification, which is much faster and more accurate than visually scanning through stored images. The text format allows for efficient indexing and searching operations.
